San you could be pickin up black sand, now on the GMT it has section on the meter that measures the black sand, now acording to the manual if you follow thw black sand from one end to the other in 1 area the reading drops and that usually indicates where the fine gold deposits build up, With the MXT in the prospect mode you can do the same by leaveing the machine in auto trac and watch the
ground meter area on the screen where it says GND=?? , you can use the MXT in the relic mode or the prospect mode when prospecting
also in this mode you've got the iron proberbility meter on both machines. The MXT will give you more choices of places to hunt but
the GMT will not like the Beach because of the high frequency and has no discrimination apart from the iron proberbility meter.
